Specification of Letters Patent.

Patented March 12, 1907.

Original application filed June 15, 1906, flerial No. 321,853. Dividelland this application filed January 17,1907- Serial No. 352,784.

To all whom it wwby concern.-

Be it known that I, EMIL RICHTER, a subj ect of the German Emperor,residing at Zabrze, Germany, have invented certain new and usefulImprovements in Apparatus for Aspirating, Treating, and Forcing Liquids,of which the following is a specification.

This application is a division of the application filed June 15, 1906,Serial No. 321,853.

The present invention relates to improvements in apparatus foraspirating, treating, and forcing fluids, in which the fluids to beacted on are brought in contact with a jet of the working fluid in thewell-known manner. An annular inlet-nozzle for the jet of working fluidis arranged in combination with annular mixing-nozzles for the fluids tobe treated. The working jet is given an annular or cylindrical form, andnot only the outer surface, but also the inner surface of the same, isutilized to produce an operative effect.

In order to make the invention more readily understood, I haveillustrated it in the accompanying drawing, in which Figure 1 is avertical sectional elevation of the apparatus. Figs. 2 and 3 representdetail sectional elevations of modifications.

If in suction apparatus steam is brought into contact with a coolerfluid, the former condenses, causing the formation of a vacuum,which isfilled again by the fluid flowing thereto. The more complete and rapidthe condensation the more energetic is the flow or suction. Forproducing perfect condensation a sufficient quantity of the cooler fluidmust be present and the contact between the latter and the steam must beintimate and widespread. In the case of an ordinary steam-jet the coreof the same is not perfectly reached by the cooler fluid, so thatcondensation of the core of the jet is slight. Also if steam is broughtinto contact with a solid jet of water the core of the water-jet is notoperative in the condensation process.

By means of the present invention a more perfect condensationisproduced, as the annular or cylindrical jet of working fluid isoperative both on its inner as on its outer surfaces and is brought intointimate contact with considerably larger quantities of cooler fluidthan would be possible with a solid jet.

The improved apparatus can. be used for forwarding great quantities ofsteam, water, air, gas, and the like and also for cleansing, or

for the absorption of gases by fluids, for miX ing various gases andfluids, for condensing steam by fluids, and for various other purposes.If the apparatus is used, for instance, for airing and removing the dustfrom rooms, at the outer and inner circumferential face of the annularworking jet air is drawn up and the air and dust particles taken with itinto a common collectingchamber. By means of the improved apparatus foulair or dust-filled air can be removed from residential or other rooms,as is done by ordinary exhausters. With the ordinary exhauster the airdrawn off is replaced by fresh air, which enters the room to beventilated principally through badly-fitting parts of windows and doors.Apart from the fact that drafts are consequently produced the air is notfreed from dust. These inconveniences are overcome by the presentapparatus by causing the inner cylindrical face and the outercylindrical face of the working jet to operate on different sources. Thejet is subsequently divided into an inner and outer part, which can beconveyed away separately.

The working jet draws out the foul air and simultaneously supplies freshair to the room without causing draft or dust clouds, and the apparatuscan be operated bywater-pressure, air-pressure, steam, or the like.

In the drawings three forms of the apparatus for ventilating andair-cleansing are shown. Through the passage 2, Fig. 1, the apparatus issupplied with water, which passes in the form of an annular jet throughthe annular passage 0 of the nozzle 3 and from thence to the annularpassage cl of the nozzle 41. The inner surface of the annular workingjet communicates, by means of a pipe 18, with the room to be ventilated,and the outer surface communicates, through the pipe f, with the openair.

By the action of the working jet passing through the nozzles foul anddusty air is drawn up at the inner periphery of the jet and fresh air atthe outer.

Immediately on entering the nozzle 4 the annular working jet strikes onthe dividingwall 23, arranged therein, and is split by the latter intoan outer part, forming formerly the outer portion of the annular jet,and into an inner art, forming formerly the inner portion 0 the annularjet. The dividing-wall is connected to a cup 24 for catching the waterflowing out of'the nozzle 4. The outer part of the jet, carrying with itfresh air, flows into the outer part 25 of the cup 24, communicatingwith the room to be ventilated. The inner part of the jet, carrying withit the foul air, passes into the inner part 26 of the cup. From theouter part of the cup the fresh air flows into the room, and the waterpasses through openings 27 into the inner part 26 of the cup, passingfrom thence, together with the water always in 26 and also the foul air,into the waste-pipe 28. If the working jet consists of compressed air,the cup 24 is, as shown in Fig. 2, provided with a filter 29, by meansof which all dust is completely retained.

If it is desired to introduce pure air free from dust and more or lesssaturated with moisture into residential rooms, work-rooms or the like,the apparatus is operated by steam and is constructed as shown in Fig.3. Steam and air flow through the vertical sieves 30. The steamcondenses gradually in its passage, so that through the last sieve dampair only flows. The condensed steam flows, as in Fig. 1, to a centralwaste-pipe.

What I claim as new is 1. In an apparatus of the character describedcomprising means ior producing an annular jet of fluid under pressure,the combination therewith of means for dividing said jet into twoseparate annular jets one within the other, substantially as described.

2. In an apparatus of the character described comprising means forproducing an annular jet of fluid under pressure, the combinationtherewith of an annular wall for dividing said jet into two separateannular jets one within the other, substantially as described. 1

3. In an apparatus of the character described comprising a casing and aplurality of nozzles having annular openings arranged in series in thecasing and separated from each other, the combination therewith of meansin one nozzle for separating an annular jet from a preceding nozzle intotwo separate annular jets, substantially as described.

4. In an apparatus of the character described comprising a casing and aplurality of nozzles having annular openings arranged in series in thecasing and separated from each other, the combination therewith of anannular dividing-wall in one nozzle for separating an annular jet from apreceding nozzle into two separate annular jets, substan tially asdescribed.

5. In an apparatus of the character de- I scribed comprising a casingand a plurality of nozzles having annular openings arranged [I1 seriesin the casing and separated from each other, the combination therewithof an annular dividing-wall in one nozzle for separating an annular jetfrom a preceding nozzle into two separate annular jets, sald dividingwall separating two receiving-chambers which communicate through saidwall, substantially as described.

In testimony whereof I afliX my signature in presence of two witnesses.
